Printer Friendly Forum Posts - viper 5901 wiring into 94 celica

Started a google doc with the wiring diagram and color codes for the car. I have a lot hooked up and the alarm works perfectly so far, but I need help with the remote start and power lock and unlock. Any help is appreciated and please edit the Google Doc, but if you do change things change the color so I know that it was someone else. Thank you for your time and help.

First of all, is it a standard or automatic?

I am working over your document now with the connections you should make. Give me a few minutes to get through it all...

Oh sorry it is a 1994 Toyota celica GT with a Manual Transmission.

Well i got the lock and unlock to work. But the remote start is not working. Just says remote start error on the remote. Also when I start the car the starter continues to run even after Ive released the key. I disconnected the car side starter wire and it has stopped. HELP!

It is doing that with the key without activating the remote start? Check all of your connections. It sounds like you have a short between one of your ignition/accessory wires and your starter wire. Did you connect tach and program / learn it?
And did you test every single connection?

Also, where and how did you ground the unit?

Yes without touching the remote start it would do that. I checked everything twice. No shorts, the only possible problem is that H3/7 and h3/8 are both going to IGN 2 as that is what is says on the viper supplied diagram. The unit is ground with a wire connector directly to the chassis, it is a good ground.

No, H3/8 is the flex relay input only required if the ignition wire needs to be disconnected. It does not get a connection.

Would that cause the starter to keep running even after the key isnt turned?

Trying to picture it, I don't think it would, but it doesn't hurt to correct it anyways. With the starter wire disconnected from the vehicle start wire, connect your DMM to the starter wire off the unit and see if it is showing voltage when you turn the key on.

Ok here is how H3 is wired:
1-Ignition one, black with orange stripe
2-12v
3-Accesory-Grey
4-Starter wire near starter
5-starter wire near ignition
6-12v
7-Ignition 2
8-not connected
9-12v

I do not have 12v coming out of violet(4) when the key is ON, because then the starter would run when the key was on even before turning the key. But I just reconnected and tried to start again, same thing, but after it runs for a few seconds it starts to stop and eventually stops completely.

Maybe I misunderstood your issue. I though that your problem was that the starter was cranking whenever you turned the key to on? What exactly happens with everything connected when you use the key to start the vehicle, and what happens when you try to remote start it?

With everything hooked up, the way i stated before for H3, and by the document for all the others. The starter continues to crank even after its running and the key isnt turning to the start position. The remote start does not work at all, i just get remote start error on the remote.

so you turn the key to "on" and its normal, but if you turn it to "start" then return the key to "on", the starter continues to crank? But if you disconnect the violet wire from the remote start everything returns to normal? That is a very odd issue. Try reconnecting the factory starter wire together, leave the green wire out of the equation, and reconnect the violet wire to the vehicle start wire and see what you get.

Also, how did you end up bypassing the clutch? Which method did you use?

Yes that is correct, alright ill disconnect the key side starter wire and put the car side starter wire back on. But even though this is a problem, why isnt the remote start working? I just bridged the clutch connection for the time being. If it is ever a problem ill put a relay in.

We are better off trying to figure out this problem then when we can have the connections all made and not have other problems we can start figuring out the remote start.

With the factory starter wire reconnected, connect the violet wire and then undo the clutch switch. Lets rule out the clutch switch first.

As long as you've made every connection exactly as in the diagram you posted, and you tested to verify each wire, we need to first figure out why the car isn't working properly with the key first. Regardless of the remote starter, the vehicle should act 100% normal with the key... which it is not.

With the violet wire disconnected the car is fine, so its something to do with the remote start obviously. The clutch has nothing do with it it seems to me.

But if you tested the violet wire while it was disconnected and it does not show voltage when you are having the issue then you have a major issue... If the violet wire was showing 12volts when returning the key then I would say its a bad unit or something causing the unit to output voltage on the violet wire... but there is something else going on; which is why i figure we should eliminate what we can. Even if its doubtful that it is the cause of the issue.

Also, its possible that the clutch switch is seeing an extended signal and backfeeding to the ignition which is causing the starter to stay engaged. I still doubt that is what is happening, but its something that doesn't hurt to check and eliminate.

My thoughts are when i turn the key to start the car electricity is being sent through the violet wire and into the brain. And then when i release the key that energy keeps the starter turning even though the key is released, and the brain acts as a sort of battery for a few seconds. That is just what it seems like to me as the car has never ever had any issues with the starting system before this.

If the ground on the unit is good then the unit should not act anything like a battery. The wires coming off the heavy gauge harness are all driven by internal relays... which should only be switched when the proper activation is sent. The relay for the violet wire is not activated by anything but the activation input and the remote. So just having it connected and not activating the starter should not cause any of this.

Hooked the clutch switch up and then reconnected the viper. Same thing with the constant starter until i release the clutch and it cuts the power. Then if i reapply the clutch it does not trigger the starter again. With everything hooked up, I press the remote start, it says remote start error, then the brain clicked 7 times, sounded like a relay clicking to me. Happens every time i hit the remote start. Any ideas?

7 flashes indicates you have not set it up for reservation mode.

read the manual to set reservation mode. make sure tach, foot brake, ignition, ebrake and clutch bypass have been done.

Ok so I still have this issue with the starter continuing to spin even after i release the key with the violet wire is hooked up. The clutch switch was re installed just like OEM and of course the starter stops when i release the clutch, and does not start again when i push the clutch down. Why is this wire causing the starter to continue to turn?

you must be wiring something wrong. its easier to diagnose from the beginning. meaning rip it all out and start from scratch.

The alarm is wired the exact way that it is shown in the document. I am 110% sure of that. So unless someone can find something wrong with the wiring configuration I wont be tearing the entire thing out.

well lets state the obvious.
1) we cannot see your work/wiring so we cannot determine the wiring problem.
2) the alarm wired exactly "shown in the document," i hope you tested all your wires.
3) your 110% doesn't mean anything, as it still doesn't work now does it?

not trying to be a sarcastic a-hole, but realistically, cut your losses, rip it out and start over. your install would be less time consuming as you have the wires as "shown in the document".

Just my .2 cents for what its worth.

I installed a viper 5901 into my 94 celica GT a few months ago but was never able to get the remote start to work. Everything else works fine but when I hit the remote start I get a remote start error on the remote and a relay inside the brain clicks 7 times. I am told that 7 clicks means it is in reservation mode. Any ideas on how to get it out of reservation mode and make the damn thing work? I have searched all over but cannot find anything about the reservation mode.

How it is wired up:
https://docs.google.com/document/d/1usKZBjVkvwjoCn2zSnCVI12aRlhkYFkEBrFCr_Ryk0k/edit?pli=1

Thank you.

Is this celica a manual transmission? I believe the manual for the 5901 is posted on this site in the downloads section

Yes its a manual. I have all the documentation for the 5901 and have searched every one for "reservation mode" with no avail.

7 light flashes means its in manual transmission mode but reservation mode has not been initialised.

If the vehicle has a manual transmission the proper steps must be followed

before leaving the parked vehicle or the remote start feature is disabled.

1. Make sure the engine is running and the doors on the vehicle are closed.

2. Put the transmission in neutral.

3. Press on the foot brake in the vehicle.

4. Apply the emergency brake.

5. Release the foot brake.

Note: Pressing the brake pedal again after this step will disable the remote start feature.

6. Within 15 seconds activate the remote start from the remote.

7. The parking lights flash 5-times confirming that the remote start is active.

If the parking lights do not flash 5-times, then repeat steps 1 - 6.

8. Turn off the ignition (the car stays running when key is turned off).

9. exit vehicle

10. Arm the alarm (the vehicle should shut off when arming the system).

if the alarm is triggered whilst armed then the now set reservation mode will be cancelled as the alarm assumes someone may have gained access into the vehicle and potentially could have knocked the transmission into gear which would be a potential risk if remote started so you would have to disarm and go through the steps from 1 to 10 again after an alarm trigger

page 28 of the user/owners guide in case its needed for future reference

Additional info : ( From 5901 Install Guide )

• Remote start MTS mode failure
The remote emits a failure notification when trying to enable the manual transmission
mode or the vehicle fails to stay remote started when the key is turned off.
Possible causes are:
• Hood Open (gray wire).
• Foot Brake active (brown wire).
• No Parking Brake input, BLACK/ white neutral safety wire not showing ground with parking brake set.
• Tachometer is not hooked up or programmed. ****
• The unit has not been programmed for tachometer mode ****
• Toggle switch not installed or not in the ON position.

As you can see, the Viper monitors and uses the following signals to enable Manual Transmission Mode :
Neutral Safety Switch input, Brake Pedal and Door Trigger ( either + or - ) All of these inputs must be connected.

**** As noted, for Manual Tranmission Mode, the Vipers Engine Checking Mode must be set to Tach ( Menu 3, Item 2,
Option 4 ) and the Tach Learn process successfully completed.

Soldering is fun!

Ok I am almost positive I have done those steps before and nothing happened, so ill check all my wiring today. My other issue is the parking lights are not hooked up, so I dont know when they flash. The person that helped me install the alarm(from here) seemed to imply they are not required. If someone could look the wiring over and tell me which wires need to be connected for the parking lights to work I would greatly appreciate it. Thank you the12volt.com!!!!

Link to the wiring

Parking Lights : Set the Vipers internal Parking Light fuse/jumper to (-)

Locate and verify this wire : Parking Lights (-) Light Green @ steering column

Connect the Vipers H1/11 White wire to the above wire. ( H1/4 is not used.)

Soldering is fun!

Ok so I got the parking wires all working now. However now when I have everything fully hooked up and the clutch switch just simply shorted when I turn the key to start the car normally the starter just continues to spin and I have to unhook the battery. I am thinking I have something setup wrong with h3.

Here is the diagram:
posted_image

The questionable wires are H3/4 which I have connected directly to the start signal wire in the engine bay. Correct or not?

h3/5 is hooked up to to the wire that is said to be starter near the ignition itself.

H3/2,h3/6 and h3/9 are all connected directly to 12 volts. Correct or not?

All connections should be made at the steering column / ignition switch harness.
All wires should be verified before making any connections. ( Info from Bulldog Security.)

Viper H3 harness     '94 Celica
H3/1 PINK (+) IGNITION 1 INPUT/OUTPUT    BLACK/ Orange @ Ignition Switch
H3/2 RED / WHITE (+) FUSED (30A)     White @ Ignition Switch
H3/3 ORANGE (+) ACCESSORY OUTPUT       Gray @ Ignition Switch
H3/4 VIOLET (+) STARTER OUTPUT (CAR SIDE)     BLACK/ White @ Ignition Switch - cut **
H3/5 GREEN (+) STARTER INPUT (KEY SIDE)         BLACK/ White @ Ignition Switch - cut **
H3/6 RED (+) FUSED (30A) IGNITION 1 INPUT         BLACK/ Red @ Ignition Switch
H3/7 PINK/WHITE (+) IGNITION 2        Blue/Red @ Ignition Switch ***
H3/8 PINK/BLACK (+) FLEX RELAY 87A         Not Used
H3/9 RED / BLACK (+) FUSED (30A)    White @ Ignition Switch
H3/10 NC (no connection)

** Note that Starter Kill / Anti-Grind is optional. If you don't want / need this
feature, do not cut the Celica's BLACK/ White Starter wire and only connect / use
the Vipers H3/4 Violet wire ( H3/5 would not be connected / used ).

*** Viper default is H3/7 = Ignition2 Verify this programming option.

Very IMPORTANT warning :

"Just shorting" the clutch pedal interlock switch is very bad. Your car
will now start with the key, without the clutch pedal depressed. This is
very dangerous if the transmission is not in neutral. Please reference
Note 3 from the original instructions that were given in the link you posted
and implement that relay for safeties sake.

Soldering is fun!

So I connected violet and green to black and white and i fixed the constant starting issue. I also checked the tach wire and made the brain "learn" the tach signal, which im guessing worked as I held the control button for 3 seconds and the LED came on and the brain clicked once.

I then attempted to set reservation mode and it did not work once again so I put the ebrake wire (h2/18) to constant ground thinking maybe that was it. Nope. There are also 2 green with white striped wires(Brake signal) in the kick panel, and ive connected it to both and neither worked.

The neutral safety switch is to ON coming off the brain.

With the key ON when I push the brake down I am not getting any power at all to the green with white wire....

Green and white is grounded, regardless if the brake is up or down. The other larger GREEN / WHITE wire goes into the door, so it cannot be the wire.

The Vipers H2/17 Brown wire must be connected for remote start operation, especially with Manual Transmission
Mode. Always test the suspect wire with a Digital Multi Meter prior to connecting the Vipers Brown wire. The
easiest place to locate this GREEN / WHITE wire is at the Brake Pedal switch connector, at the top of the Brake
Pedal. It should show a +12V signal when the pedal is depressed.

-------------
Soldering is fun!

Ok I wired directly to the switch. Now if I start the car, push the brake in, set the ebrake, release the brake and then push remote start it works! Then I remove the key and exit the car(with the car still running). Then push lock which is what it says to do, the car stops(like it is supposed to) then After about 5 seconds the remote says remote start error. Then if I try to remote start it again i get an error with 7 clicks.

So close and yet so far... posted_image

Could be a lot of things. I am not a Viper person so I my not be able to
help. My first thoughts are that something is "kicking you out" of Reservation
Mode. I would double check all my wiring and connections to ensure that all
solder connections are good, everything is well insulated and no wires are
chaffed or touching metal.

Did you re-program the Viper to Tach Mode by setting Menu 3, Item 2 to Option 4?

Also don't forget to correctly wire the clutch switch bypass.

Hopefully someone with more Viper experience can assist.

Soldering is fun!

Tell me about it haha. I disconnected green and there is no difference. The brain has a tach signal because when i start the car and hold the control button down and wait 3 seconds the LED lights up to indicate it has learned the tach signal, however I do get a relay click right after I let go of the button but I would think its just adjusting. Due to it running when i take the key out I would think all the IGN wires, doors, grounds , and 12 volts are fine. I will recheck the ebrake just to be safe though.

The manual says I should be able to manually start the car by putting a ground pulse to H1/10, which is not connected to anything. I did this and got nothing.

Also the ebrake wire seems to be grounded even if the ebrake is down..But the ebrake plug itself only grounds when up. The ebrake light works fine.

I don't think H1/10 will work in Manual Transmission Mode or at least
won't work if you are not properly set up in Reservation Mode.

Not to put you on the spot but did you actually go into the Viper
programming procedure and change Engine Checking to Tach mode?

Menu 3, Item 2 to Option 4

-------------
Soldering is fun!

No problem. I think it is in tach mode due to what this says from the manual:

To learn the tach signal:
1. Start the vehicle with the key. Within 5 seconds, press and hold the Control button.
2. After 3 seconds the status LED on your Control Center lights constant when the tach signal is learned.
3. Release the Control button.
Note: When the tachometer is programmed, the main unit automatically enters the Tachometer engine checking mode.

I cant seem to get into system features. I lock the car, then unlock, open the door, turn the key to ON, then back off and out. Then hold the control button, and nothing happens. No beeps or anything to program the alarm.

It was brought to my attention that it is switching out of reservation mode possibly due to the doors not being hooked up properly? I have the door triggers in place that are connected to 2 wires in the kick panel that were already tapped into from a previous alarm wire up. But they work to unlock and lock so I did not go through the wiring described in the document. Does anyone have any idea how to properly wire the doors without having to buy diodes? Or are they required?

All door wire, RED / white with silver traces plug at base of right hand kick panel on right hand drive cars, might be the other side on left hand drive, TEST. No diodes required just connect to the unit's green (+) door trigger wire.
